ROBINSON BULMER, OF BURLINGTON, IOWA.

SWINGING AND SLIDING GATE HINGE.

SPECIFICATION forming' part of Letters Patent No. 430,618, dated .Tune 24, 1890.

Application filed January 17, 1890. Serial No. 337,196. (No model.)

T0 all whom it may concern:

Be it known that I, ROBINsoN BULMER, a citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Hinges for Swinging and Sliding Gates; and I do hereby declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same' This invention relates to novel and useful improvemcnts in hinges; and it consists in the novel construction and arrangement of a grooved roller, its axle, and an attaching-plate carrying a supporting-arm designed to be used in combination with said roller, Whereby a combined roller and hinge is produced, designed to be used with a gate capable of either sliding or swinging, all as will be hereafter more fully explained, and particularly pointed out in the appended claim.

The annexed drawings, to which reference is made` fully illustrate my invention, in which- Figure 1 represents a Vertical central sectional view of my device. Fig. 2 is a rear view of the roller. Figi 3 is a plan view of the attaching-plate with its supporting-arm. Fig. 4 is a sectional view, and Fig. 5 is a view of the axle.

Referring by letter to the accompanying drawings, A designates the combined roller and hinge, consisting of the roller a, having the groove b, which supports and guides a gate in its movements. This roller has its bearing on a journal c, which latter is provided with a pin or stud d on its inner end, which ongages an eye or perforation e in the arm f of the attaching-plate g, which latter also has perforations h h, through which nails or screws pass, whereby said plate is secured to a gate-post. The inner face of this roller is cut away, forming a concaved central opening t, surrounding the opening or bearingj for the journal, and within this enlarged opening i the end 7a of the arm on the supporting-plate projects. The under side of this arm f is convexed, corresponding with the concaved enlarged opening in the roller, as shown at Z, and the same has its play therein, the concaved portion preventing the journal from becoming detaohed from said arm. Thus it will be seen that this journal is pivoted to the supporting-arm, and the outer end of said journal has a pin fm, which passes through a perforation n, thus retaining the roller in position on said journal, and by the construction of the parts herein shown a gate can be readily and quickly lnounted thereon, and the peculiar construction permits a gate to slide back and forth, and at the same time allows the gate to swing open and shut.

In applying my hinge I secure it by its plate to a post, and then mount the gate on the roller, usually between the second and third horizontal rails near the top of the said gate, the second rail or bar resting in the groove in the roller, after which the gate is permitted by the pivotal connection between the arm on the plate and the journal to be moved back or forth and also swung around.

A hinge as herein described is durable, ornamental, and cheap to manufacture.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination, with the plate provided with the arm having the convex surface and perforated, of the journal provided with the stud engaging said perforation and the roller having the concave surface engaging the convex arm, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ROBINSON BULMER.
